in Hosted Private Cloud

SAN ANTONIO--(BUSINESS WIRE)--Rackspace® Hosting, (NYSE: RAX), the
open cloud company, today announced it has been named, along with
one other vendor, a Top Performer by Forrester Research Inc. in its new
report, “The Forrester Wave™: Hosted Private Cloud Q1 2013.” The report
evaluated Rackspace’s full Private
Cloud portfolio including Managed Virtualization and Rackspace
Managed Private Cloud powered by OpenStack.

As part of the research firm’s analysis, Forrester evaluated the
strengths and weaknesses of eight selected cloud computing companies
against 25 criteria. Rackspace received among the highest scores of the
eight cloud companies when evaluated in the subcategories for planned
enhancements and the highest score among all vendors for third-party
ecosystem. The Forrester report also noted that “Rackspace brings its
experience from the hosting and public cloud space to this market,
giving it significant geographic presence, a reputation for fantastic
customer support, and a large existing customer base from which to draw.”

“The Rackspace open cloud continues to offer choice and innovation to
our customers. We’re very pleased to receive recognition from Forrester
for our Private Cloud efforts with Managed Virtualization and Rackspace
Private Cloud powered by OpenStack,” said John Engates, CTO at
Rackspace. “The software is free and available to anyone to use in any
data center of their choosing. Customers choosing Rackspace Private
Cloud get the benefit of using the same code that powers the world’s
largest OpenStack cloud along with dozens of private clouds. They can
choose to deploy and run it themselves, or they can choose to let
Rackspace support or even run it remotely for them in their data center
or in ours.”

Rackspace, co-founder of OpenStack,
today is running the largest, enterprise-ready open cloud platform in
the world. The Rackspace open cloud based on OpenStack allows true
choice and control without the fear of being locked-in to one vendor’s
technology. With open standards and open source based enterprise and
mobile computing now impacting the total IT landscape to a deeper and
more expansive level than ever before, Rackspace’s vocal support of an
open approach and open cloud development strategy has clearly helped the
company stand above its competitors across the market today.

According to Forrester Research, “[As many as] 46 percent of enterprises
are prioritizing investments in private clouds in 2013. While slightly
more than half plan to build a private cloud in their own data center,
more than 25 percent said they prefer to rent one.”

Hosted private cloud is an increasingly popular IaaS deployment model
that couples the agility, expertise, and shifted infrastructure
responsibility of public cloud with privacy and the configuration
customization of private cloud.

Tapping into Rackspace’s progressive and strategic development of open
cloud computing architectures designed to free customers from the
dangers of vendor lock-in, the Forrester report said that Rackspace’s
“strategy and market presence push it ahead” in the independent research
firm’s analysis of hosted private cloud providers.
